Abstract (en)
[origin: WO2005016840A2] The invention relates to glasses with a composition of the sodalime type to which the following colouring elements are added with the given weight proportions: Fe2O3 : 1.1 to 1.5% (total iron in the composition), Co : 150 to 200 ppm, Cr2O3 : 25 to 100 ppm, Se : 10 to 50 ppm, MnO: less than 600 ppm and TiO2 : less than 0.1 %. The components of the composition are selected in such proportions that the light transmission for a thickness of 4mm, TLA4, is less than 20%, and the energy transmission TE4 (Moon) is less than 20%.
